GILLETTE SAFETY RAZOR COMPANY, TION OF DELAWARE OF BOSTON,MASSACHUSETTS, A CORPORA- SAFETY RAZOR Application filed November 19,1927. Serial No. 234,356.

My invention relates to improvements in safety razors of the classrovided with a rockable blade holder, and with a guard movably' suported with respect to the blade holder For cooperation with the bladefor shavin which blade holder and guard may be fol ed in a compactposition for transportation and storage.

An object of my invention is to provide improved means to retain a guardin cooperation with a blade and blade holder for shaving and in aposition folded with respect to the frame, an to retain the guard inanother position remote from the blade holder to permit the latter to berocked for sharpening the blade.

Another object is to rovide simple means to cause the blade hol er to beretained by the guard when the blade is in shaving relation to theguard.

Another object is to permit the blade to be displaced from shavingrelation to the guard in case the blade used in the blade holder is notro(perly organized for cooperation with the iila e holder to be retainedin shaving relation to the ard.

My invention also com rises novel details of improvement that will cmore fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming a parthereof, wherem-- Fig. 1 is an edge view of my improved razor;

Similar numerals of reference indicate corresponding parts in theseveral views.

The main frame 1 of the razor may be of any suitable construction, thesame being shown comprising a base 1a and spaced uprights 1?). At 3 is ablade holder pivotally supported by and between the uprights 1b adaptedto detachably retain a blade 4. The blade holder may be pivotallysupported in the main frame in any desired way. In the exampleillustrated the blade holder is provided with pivots 5 at oppositecorners journaled in holes in the uprights 112. At 6 is a rollerjournaled upon and between the uprights 16, which roller is operativelyconnected with the blade holder for rotating the latter. In the exampleillustrated the roller is provided with gears 7 that are in mesh withgears 8 secured to the blade holder, whereby when the roller isreciprocated along a stroping or sharpening surface 9 the roller willrotated for correspondingly rocking the blade holder and the blade. Aguard member includes a guard 10 for the blade edge provided with spacedside arms or webs 11 that are pivotally supported upon and between theuprights lb by means of pivots 12, which pivots operate in slots 13 inthe uprights 16, and thereby the guard member may have some lateralmovement. The guard is shown provided with stops 10a adapted to engagethe blade edge when the blade and guard are in shaving position, (Fi 1).At-

14 is a spring carried by the main rame and having opposite ends free tocooperate with the guard member. Said spring may be secured to the framein any desired way. In the exam le illustrated a handle 15 is secured tot e base 1a andengages spring 14 to secure the latter to base 1a, saidparts bein shown riveted together at 15a. The guar 9 member is ada tedto engage spring 14 to retain the guar member in various positions. Thearms 11 of the guard member are shown provided with rojecting portions11a adapt- I e'd to engage t e end portions of spring 14 i when theguard and the blade are assembled shaving position so that the springwill retain the guard in suck. osition, at which time projections 10' oft e guard member enter recesses 16 at the adjacent corners of the bladeholder (Fi s. 1 and 5), to retain the uard and t e b ade holder inshaving relation, the guard being movable in a direction transverse tothe cutting edge of the blade to engage and disengage the projections10' and the recesses 16. The action of spring 14 upon the guard memberwill retain the.

blade holder and guard from relative movement while the blade edgeengages the stops 10a of the uard in shaving position, (Fig. 1). Thepivots 12 operating in the slots 13 permit the guard to have easy rotarymotion against spring 14 as well as to accommodate the guard to itsvarious positions. The guard member is shown provided with a fingerpiece 17, which may be stamped from the metal of the guard member, tofacilitate operation of the latter. A projection 18 on one of theuprights 1b is in position to limit the forward movement of the guardrelatively to the main frame. When the guard is to be assembled inshaving relation to the blade the finger piece 17 may be pushed toadvance the guard through the frame and the projection 18 will stop themovement of the guard, whereupon the blade may be rested u n theguard,(Fig. 4), and when the guar member is released the spring 14, byacting upon the projections 11a, will cause the uar to move toward theblade and the bla e holder to assemble the parts, as in Fig. 1. Theguard member is also provided with a relatively flat portion 19 that isadapted to engage spring 14 when the guard is in a folded posit1on withrespect to frame 1, as indicated in Fig. 2 and the blade holder with theblade may also be folded within the frame between the uprights 16, (Fig.2), for compact assembly of the parts for stora e and transportation.The guard member 1s also provided with a relatively fiat portion 20which is adapted to engage spring 14 when the guard is moved out of themain frame, as indicated is Fig. 10, to permit stropping of the blade ege.

The blade holder may be of any desired construction adapted todetachably retain the blade 4. In the example illustrated the bladeholder is substantially the same as the blade holder set forth in myapplicationfiled October 22, 1927, Serial No.227,884. As illustrated theblade holder comprises two main members 21 and 22, the member 21 havinglaterally disposed webs 23 at its ends from which keepers or clips 24extend substantially parallel with and s aced from the member 21, whichparts may formed from a single sheet of metal. The member 22 isoperatively fitted between the projections or webs 23, provided at itsends with projections 25 which extend into slots 26 having ofisetportions 26', (Fi 10),

which slots permit the member 22 to s ide as well as to rotate or swingpivotally relatively to member 21. The edge portions of member 22 areadapted to fit in the spaces between the member 21 and the keepers 24when the blade is assembled in shaving position to retain the partstogether, (Fig. 7). The member 21 is provided with spaced projections orstuds 27 adapted to enter holes 4a in the blade to retain the latter inshaving position, and the member 22 is provided with slots 22a toreceive said projections and permit member 22 to slide relatively tosaid projections. The member 21 is shown provided with abutments 21aattached to the inner edge of said member in position to engage theinner edge of the member against which the heel of the blade may bearwhen the latter is inserted angularly between the members 21 and 22 toregister the blade openings 4a with the projections 27, as illustrated1n Fig. 9. When the parts 21 and 22 are, clamped against. the blade andthe projections 27 are in the openings 4a of the blade the latter willbe retained in proper position in the blade holder and against thespring thrust of the stops 10a of the guard. In the eventthat a bladeshould be made by an unauthorized manufacturer havin openings at 4a toolarge to snugly fit the pro ections 27 the blade would be liable toslide rearwardly within the blade holder, and in order that the bladeedge may move sutficiently far away from the guard to preclude propershaving the roller 6 is provided with a longitudinal slot 6a located insuch position that when the guard and the blade holder are assembled forshaving, as in Fig. 1, said slot will oppose the inner edge or heel ofthe blade, whereby such unauthorized blade may slide at its rear edgeinto said slot and thereby the blade edge will be displaced so far backfrom the guard as to preclude proper shaving, as illustrated in issumingthat the parts are in the folded position of Fig. 2 and it is desired toassemble the blade and the guard for shaving, the guard member may bepushed through the frame and in turn said member will push out the bladeholder and the blade so that the blade will rest upon theguard, asshownin Fig. 4, the projection 18 stopping the advance of the guardmember through the frame and the projecting portion 11a of the guardmember will bear upon spring 14. When the guard member is released saidspring will operate against the guard member to cause the guard and theprojections 10 to advance toward the blade and the blade holderrespectively. The guard stops 10a will engage the blade edge and theprojections 10 will enter the recesses 16 of the blade holder. When itis desired to release the guard from the blade holder the guard will bepushed away from the blade and the latter will be moved outitotheframe-outof.

wardly to permit the guard to pass under the blade. The portion 19 ofthe member will engage spring 14 to retain the parts when folded, as inFig. 2. When it is desired to sharpen the blade edge the guard memberwill be moved to the position shown in Fig. to be retained by the spring14 bearing against the portion 20 of the uard member, and the razor willbe positione over the sharpening surface 9 with the roller 6 thereon, asin Fig. 10. The razor may then be reciprocated along surface 9. wherebythe roller will cause rocking of he blade and the blade holder throu hframe 1, so that opposite sides of the blade edge will 15 be draggedalong the sharpening surface for stro ping the blade edge, the bladeholder and bla e being caused to rock from one side to another at thecommencement of each stroke of the razor along surface 9.
